Safety Information

We use note, caution and warning symbols throughout this book to draw your attention to im­portant operational and safety information.

A “NOTE” marks a short message to alert you to an important detail.

A “CAUTION” safety alert appears with information that is important for protecting your
equipment and performance. Be especially careful to read and follow all cautions that apply
to your application.

A “WARNING” safety alert appears with information that is important for protecting you,
others and equipment from damage. Pay very close attention to all warnings that apply to
your application.

The safety alert symbol, ç (an exclamation point in a triangle) precedes a general CAUTION
or WARNING statement.

The electrical hazard symbol, Ó (a lightning bolt in a triangle) precedes an electric shock
hazard CAUTION or WARNING safety statement.

Technical Assistance

If you encounter a problem with your Watlow controller, review your configuration informa­tion to verify that your selections are consistent with your application: inputs, outputs,
alarms, limits, etc. If the problem persists, you can get technical assistance from your local Wat­low representative (see back cover), by e-mailing your questions to wintec

[e-mail]
or by dialing [phone] between 7 a.m. and 5 p.m., Central Standard Time (CST). Ask
for for an Applications Engineer. Please have the following information available when call­ing:

• Complete model number • All configuration information

• User’s Manual • Factory Page

Warranty

The Series SD is manufactured by ISO 9001-registered processes and is backed by a three­year warranty.

Return Material Authorization (RMA)

1. Call Watlow Customer Service, [phone], for a Return Material Authorization
(RMA) number before returning any item for repair. If you do not know why the product
failed, contact an Application Engineer or Product Manager. All RMA’s require:

• Ship to address • Bill to address

• Contact name • Phone number

• Method of return shipment • Your P.O. number

• Detailed description of the problem • Any special instructions

• Name and phone number of person returning the product.

2. Prior approval and an RMA number from the Customer Service Department is required
when returning any product for credit, repair or evaluation. Make sure the RMA number is
on the outside of the carton and on all paperwork returned. Ship on a Freight Prepaid basis.

3. After we receive your return, we will examine it and try to verify the reason for returning it.

4. In cases of manufacturing defect, we will enter a repair order, replacement order or issue
credit for material returned. In cases of customer mis-use, we will provide repair costs and
request a purchase order to proceed with the repair work.

5. To return products that are not defective, goods must be be in new condition, in the origi­nal boxes and they must be returned within 120 days of receipt. A 20 percent restocking
charge is applied for all returned stock controls and accessories.

6. If the unit is unrepairable, you will receive a letter of explanation. and be given the op­tion to have the unit returned to you at your expense or to have us scrap the unit.

7. Watlow reserves the right to charge for no trouble found (NTF) returns.

Watlow Series SD Calibration ■ 6 ■ Factory and Calibration

Calibrating the Series SD

Warm up the unit for 20 minutes. To reach the cali-

bration prompts, enter the Factory Page by holding
down the Up Key ¿ and Down Key ¯ for six seconds.
Once in the Factory Page [FACT], use the Advance ‰
key to select a prompt. The last prompts on the Factory
Page are the input and output calibration prompts.

You can restore the original factory calibration with

Restore Factory Calibration [rESt] (Factory Page).

*Note: INFOSENSETMshould be turned off while verifying calibration
of the controller with a calibration source.

Thermocouple Input Procedure

Equipment

• Type J reference compensator with reference junc­tion at 0°C (32°F), or type J thermocouple calibra­tor to 0°C (32°F).

• Precision millivolt source, 0 to 50 mV minimum
range, 0.002 mV resolution.

Input Setup and Calibration

1. Connect the correct power supply to terminals 1
and 2 (see Chapter Two).

2. Connect the millivolt source to terminals 11 (-) and
10 (+) with copper wire.

3. Enter 50.00 mV from the millivolt source. Allow at
least 10 seconds to stabilize. Set Thermocouple Cal­ibration, 50 mV [tc;50] to [`yES]. Press the Ad­vance Key ‰ to store 50.000 mV input and move to
the next prompt.

4. Enter 0.000 mV from the millivolt source. Allow at
least 10 seconds to stabilize. Set Thermocouple Cal­ibration, 0 mV [tc;00] to [`yES]. Press the Ad­vance Key ‰ to store 0.000 mV input and move to
the next prompt.

5. Disconnect the millivolt source and connect the ref­erence compensator or thermocouple calibrator to
terminals 11 (-) and 10 (+). With type J thermocou­ple wire, if using a compensator, turn it on and
short the input wires. When using a type J calibra­tor, set it to simulate 0°C (32°F). Allow 10 seconds
for the controller to stabilize. Set Thermocouple
Calibration, 32° [tc;32] to [`yES]. Press the Ad­vance Key ‰ to store type J thermocouple calibra­tion and move to the next prompt.

6. Rewire for operation and verify calibration.

RTD Input Procedure

Equipment

•1 kΩ decade box with 0.01Ω resolution.

Input Setup and Calibration

1. Connect the correct power supply to terminals 1
and 2 (see Chapter 2).

2. Connect the decade box to terminals 10 (S1), 11
(S3) and 8 (S2), with 20 to 24-gauge wire.

3. Enter 15.00Ω from the decade box. Allow at least
10 seconds to stabilize. Set RTD Calibration, 15Ω

[`r;15] to [`yES]. Press the Advance Key ‰ to

store the 15.00Ω input and move to the next

prompt.

4. Enter 380.00Ω from the decade box. Allow at least
10 seconds to stabilize. Set RTD Calibration, 380Ω

[r;380] to [`yES]. Press the Advance Key ‰ to

store the 380.00Ω input and move to the next

prompt.

5. Rewire for operation and verify calibration.

Voltage Process Input Procedure

Equipment

• Precision voltage source, 0 to 10V minimum range,
with 0.001V resolution.

Input Setup and Calibration

1. Connect the correct power supply to terminals 1
and 2 (see Chapter Two).

Input

2. Connect the voltage source to terminals 11 (-) and
9 (+) of the controller.

3. Enter 1.00V from the voltage source to the con­troller. Allow at least 10 seconds to stabilize. Set In­put Calibrate, 1V [``u;1] to [`yES]. Press the Ad-
vance Key ‰ to store the 1.00V input and move to
the next prompt.

4. Enter 9.00V from the voltage source to the con­troller. Allow at least 10 seconds to stabilize. Set In­put Calibrate, 9V [``u;9] to [`yES]. Press the Ad­vance Key ‰ to store the 9.00V input and move to
the next prompt.

5. Rewire for operation and verify calibration.

Current Process Input Procedure

Equipment

• Precision current source, 0 to 20 mA range, with

0.01 mA resolution.

Input Setup and Calibration

1. Connect the correct power supply to terminals 1
and 2 (see Chapter Two).

2. Connect the current source to terminals 11(-) and
8(+).

3. Enter 4.00 mA from the current source to the con­troller. Allow at least 10 seconds to stabilize. Set In­put Calibrate, 4 mA [``A;4] to [`yES]. Press the
Advance Key ‰ to store the 4 mA input and move
to the next prompt.

4. Enter 16.00 mA from the current source to the con­troller. Allow at least 10 seconds to stabilize. Set In­put Calibrate, 16 mA [`A;16] to [`yES]. Press the
Advance Key ‰ to store the 16 mA input and move
